Description

Technical Field

[0001] This application relates to the field of linear modules, and more particularly to a mover assembly and a linear module. Background Technology

[0002] In traditional linear motor module designs, the signal feedback unit typically exists as a separate functional component, requiring a dedicated external support structure for mounting. This support is generally attached to the outside of the module's mover. This layout inevitably increases the overall lateral dimension of the module, resulting in a less compact structure. The additional space occupied by the feedback unit and its support makes it difficult to effectively reduce the overall width of the module, hindering the miniaturization and integration of the device. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a moving part assembly and a linear module.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A moving part assembly having a first direction and a second direction perpendicular to each other, comprising: The moving part body has a first mounting groove formed on its side along the first direction; A signal feedback element is disposed in the first mounting slot and connected to the moving body; The motor body is fixedly disposed on one side of the moving part body along the first direction, and the motor body and the signal feedback element are disposed on the same side; The connector is disposed at the end of the moving body along the second direction, and the connector is electrically connected to the signal feedback element and the motor body.

[0005] Furthermore, a second mounting groove is also provided on the side of the moving body along the first direction, and the second mounting groove is provided on the same side as the first mounting groove; The surface of the signal feedback element and the motor body that is away from the moving part body is flush with or forms a preset distance from the side of the moving part body along the first direction.

[0006] Furthermore, a sealant is provided in the first mounting groove, and the sealant covers the signal feedback component.

[0007] Furthermore, the moving body has a first groove along the second direction, the first groove is connected to the second mounting groove, and the connector is located at the position of the first groove.

[0008] Furthermore, a second groove is also provided on the side of the moving body along the first direction. The second groove is provided on the same side as the first mounting groove. One end of the second groove is connected to the first mounting groove, and the other end of the second groove away from the first mounting groove is connected to the second mounting groove.

[0009] This application also provides a linear module having a first direction, a second direction, and a third direction that are perpendicular to each other. The linear module includes: Base; The moving part assembly described in any one of the above descriptions is slidably disposed on the base along the second direction; A magnetic rail is fixedly disposed on the side of the base facing the moving part assembly along the first direction.

[0010] Furthermore, the base is fixedly provided with side plates at both ends along the first direction, the two side plates form a support frame, a first protective plate is installed on the support frame, and the moving part is located between the first protective plate and the base.

[0011] Furthermore, at least one cushioning pad is provided on each of the two side plates facing each other.

[0012] Furthermore, at least one sensor is provided on one side of the base along the third direction, and a sensing element is provided on one side of the moving body along the third direction. The sensor and the sensing element are located on the same side, and the sensor is located on the moving path of the sensing element.

[0013] Furthermore, a second protective plate is provided on the base, which is used to cover the magnetic track.

[0014] This application effectively reduces the width of the mover assembly in the third direction by placing the signal feedback component in the first mounting slot of the mover body and on the same side as the motor body, thus achieving a compact structure. This overcomes the problem of increased module lateral size caused by independent installation of the signal feedback unit in the prior art, which is conducive to the miniaturization and integration of the equipment. At the same time, the integrated design simplifies the assembly process, reduces independent installation and calibration procedures, and improves assembly efficiency and accuracy. In addition, the signal feedback component is built into the mounting slot, eliminating the need for additional brackets and protective covers, providing inherent protection, and reducing complexity and cost.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] This application provides a mover assembly having a first direction Z and a second direction X that are perpendicular to each other. The mover assembly includes a mover body 100, a signal feedback element 200, a motor body 300, and a connector 400.

[0025] It is understandable that the first direction Z in the above refers to the vertical direction, and the second direction X refers to the lateral movement direction of the moving body 100.

[0026] Specifically, the mover body 100 has a first mounting groove 101 on its side along the first direction Z. The signal feedback component 200 is disposed in the first mounting groove 101 and connected to the mover body 100. The motor body 300 is fixedly disposed on one side of the mover body 100 along the first direction Z. The motor body 300 and the signal feedback component 200 are disposed on the same side. The connector 400 is disposed at the end of the mover body 100 along the second direction X. The connector 400 is electrically connected to both the signal feedback component 200 and the motor body 300.

[0027] See Figure 1 and Figure 2As shown, this application also includes a third direction Y perpendicular to the first direction Z and the second direction X, and the first direction Z, the second direction X and the third direction Y are arranged perpendicularly to each other. Specifically, in order to prevent the signal feedback element 200 from being placed on the side of the moving body 100 and increasing the length of the entire linear module in the third direction Y, that is, the width direction of the module, a first mounting groove 101 is opened on one side of the moving body 100 along the first direction Z, and the signal feedback element 200 is fixed in the first mounting groove 101. Specifically, a locking hole adapted to the signal feedback element 200 can be opened on the bottom wall or inner side wall of the first mounting groove 101, and the signal feedback element 200 is locked and fixed on the moving body 100 and located in the first mounting groove 101 by screws.

[0028] It is understandable that by setting the signal feedback element 200 in the first mounting slot 101, it is not necessary to set it on the third Y-direction side of the mover body 100, thus not increasing the width of the entire linear module, which can meet the needs of equipment miniaturization and integration.

[0029] In this embodiment, the motor body 300 and the signal feedback element 200 are disposed on the same side, and a connector 400 is disposed at the second direction X end of the mover body 100. Both the signal feedback element 200 and the motor body 300 are connected to the connector 400. That is, the signal feedback element 200 and the motor body 300 are connected to the external power supply and controller through the connector 400. The connector 400 is a quick plug and has a socket adapted to the signal feedback element 200 and the motor body 300, which can quickly realize the connection with the signal feedback element 200 and the motor body 300. That is, the cable of the signal feedback element 200 and the cable of the motor body 300 are electrically connected to the connector 400 by plugging in, so as to realize the transmission of electrical energy and electrical signals.

[0030] For example, the signal feedback element 200 can be a magnetic track encoder.

[0031] In some embodiments, the mover body 100 is further provided with a second mounting groove 102 on the side along the first direction Z, and the second mounting groove 102 is disposed on the same side as the first mounting groove 101; the surface of the signal feedback element 200 and the motor body 300 facing away from the mover body 100 is flush with or forms a preset distance from the side of the mover body 100 along the first direction Z.

[0032] like Figure 1 , Figure 2 as well as Figure 3As shown, in order to enable the installation of the motor body 300, a second mounting groove 102 is formed on the surface of the mover body 100 on the same side as the first mounting groove 101. The motor body 300 is embedded and installed into the second mounting groove 102. It can be understood that the motor body 300 and the mover body 100 can also be fixedly connected by screw fastening. In this embodiment, the first mounting groove 101 and the second mounting groove 102 are formed on the same surface of the mover body 100.

[0033] When the moving body 100 moves along the second direction X, in order to prevent the signal feedback element 200 and the motor body 300 from colliding with the magnetic track 600 of the linear module and causing motion interference, in the third direction Y, the signal feedback element 200 should be completely located within the first mounting groove 101, and the signal feedback element 200 should be flush with or not exceed the surface of the first mounting groove 101, that is, the signal feedback element 200 should not protrude from the surface of the first mounting groove 101; correspondingly, the motor body 300 should be flush with or not exceed the surface of the second mounting groove 102, so that the motor body 300 will not protrude from the surface of the second mounting groove 102, thus preventing motion interference with the magnetic track 600 of the linear module.

[0034] In some embodiments, a sealant (not shown) is provided in the first mounting groove 101, and the sealant covers the signal feedback element 200.

[0035] In this embodiment, to prevent the signal feedback component 200 from shaking due to insecure mounting, after the signal feedback component 200 is installed into the first mounting groove 101, sealant can be poured into the first mounting groove 101 to wrap the signal feedback component 200. After wrapping, the sealant is cured to firmly encapsulate the signal feedback component 200 inside, thereby preventing the signal feedback component 200 from shaking and making the signal feedback component 200 more stable and reliable during use.

[0036] In some embodiments, the moving body 100 is provided with a first groove 103 along the second direction X, the first groove 103 communicates with the second mounting groove 102, and the connector 400 is disposed at the position of the first groove 103.

[0037] The moving body 100 is also provided with a second groove 104 on the side along the first direction Z. The second groove 104 is provided on the same side as the first mounting groove 101. One end of the second groove 104 is connected to the first mounting groove 101, and the other end of the second groove 104 away from the first mounting groove 101 is connected to the second mounting groove 102.

[0038] See Figure 3As shown, in order to connect the cables of the signal feedback device 200 and the motor body 300 to the connector 400 outside the mover body 100, a first groove 103 needs to be opened on the plane where the first mounting groove 101 is opened, and a second groove 104 needs to be opened at the end of the mover body 100 along the second direction X. One end of the first groove 103 is connected to the first mounting groove 101, and the other end of the first groove 103 is connected to the second mounting groove 102. The second groove 104 is connected to the second mounting groove 102. Specifically, the second groove 104 is located at the end of the mover body 100 where the first mounting groove 101 is located, that is, the second groove 104 and the first mounting groove 101 are located at the same end of the mover body 100.

[0039] Understandably, the cable of the signal feedback component 200 extends into the second mounting groove 102 through the first wire groove 103, and then connects to the connector 400 through the second wire groove 104. The cable of the signal feedback component 200 should be completely located in the first wire groove 103 and not exceed the plane in which it is opened. The cable of the motor body 300 passes through the second wire groove 104 and connects to the connector 400, thereby realizing the cable routing of the signal feedback component 200 and the motor body 300.

[0040] This application also provides a linear module, which includes a base 500, a mover assembly as described in any of the above embodiments, and a magnetic track 600.

[0041] Specifically, the mover assembly is slidably mounted on the base 500 along the second direction X, and the magnetic rail 600 is fixedly mounted on the side of the base 500 facing the mover assembly along the first direction Z.

[0042] See Figure 4 and Figure 5 As shown, the mover body 100 of the mover assembly is slidably mounted on the base 500 via components such as guide rails and sliders. The motor body 300 of the mover assembly and the magnetic rail 600 work together to make the mover body 100 move along the base 500 in the second direction X.

[0043] In some embodiments, the base 500 is fixedly provided with side plates 700 at both ends along the first direction Z, the two side plates 700 form a support frame, a first protective plate 800 is installed on the support frame, and the moving body 100 is located between the first protective plate 800 and the base 500.

[0044] Continue reading Figure 4 and Figure 5As shown, in order to prevent external dust or particles from falling onto the moving body 100 and causing damage, side plates 700 are installed at both ends of the base 500, and a first protective plate 800 is installed on the top of the two side plates 700. The first protective plate 800 blocks the top of the moving body 100 to prevent external dust from falling onto the moving body 100. In addition, when it is impacted, the first protective plate 800 can absorb the impact force to a certain extent to achieve buffering and protection, preventing the impact force from acting directly on the moving body 100.

[0045] In some embodiments, at least one cushioning pad 710 is provided on each of the two side panels 700 facing each other.

[0046] like Figure 4 and Figure 5 As shown, during the lateral movement of the moving body 100 along the second direction X, in order to prevent the moving body 100 from directly colliding with the side plate 700 and causing damage, a buffer pad 710 is installed on the side of the two side plates 700 that are close to each other. When the moving body 100 touches the buffer pad 710, the buffer pad 710 will deform to achieve buffering, thereby preventing the moving body 100 from directly colliding with the side plate 700 and causing damage.

[0047] For example, the cushioning pad 710 can be a rubber column.

[0048] In some embodiments, at least one sensor 910 is provided on one side of the base 500 along the third direction Y, and a sensor 920 is provided on one side of the mover body 100 along the third direction Y. The sensor 910 and the sensor 920 are provided on the same side, and the sensor 910 is located on the moving path of the sensor 920.

[0049] In order to enable the moving body 100 to stop precisely at different positions on the base 500, at least one sensor 910 is installed on the side of the base 500. In practice, multiple sensors 910 can be installed to achieve positioning and stopping at different positions. It can be understood that the moving body 100 will drive the sensor 920 to move, thereby triggering the signal through the sensors 910 at different positions. Specifically, the sensor 910, the signal feedback device 200, the motor body 300, etc. are connected to an external controller, and the controller controls the linkage between the various components.

[0050] For example, sensor 910 is a photoelectric sensor and sensing element 920 is a light shield.

[0051] In some embodiments, a second protective plate 1000 is provided on the base 500, which is used to cover the magnetic track 600.

[0052] It is understandable that by setting up a second protective plate 1000 to cover the magnetic rail 600, external dust particles are prevented from falling onto the magnetic rail 600 and affecting its performance.
